Product Overview
产品概述
A power supply chassis is asked to do three jobs that pull in different directions at once: carry the weight of the transformer or module stack, move heat out without sounding like a server, and let a technician read every indicator without opening anything. Most designs fail on the third one, because the display window and indicator apertures get drawn late, after the internal layout has already been frozen.
电源外壳要同时承担三件互相牵制的任务：托住变压器或模块组的重量、把热量排出去而不吵得像服务器、让技术人员不开箱就能看清每个指示灯。多数设计栽在第三点上——因为显示视窗与指示灯孔往往画得太晚，那时内部布局已经冻结了。
We build these in aluminium rather than steel for two reasons that have nothing to do with appearance: thermal spreading and weight. An aluminium shell draws heat off the mounting flanges and towards every face, so hotspot temperature drops without adding a fan. And a chassis one person can lift onto a bench is a chassis that actually gets serviced. The standard construction is sand-blasted then anodized sheet, which hides handling marks far better than a mill finish and holds up to the cleaning these units get inside industrial cabinets.
我们选用铝材而非钢材，原因与外观无关，只有两条：散热扩散与重量。铝壳能从安装法兰把热量导向各个面，因此不必增设风扇就能降低热点温度；而一个人能搬上工作台的电源箱，才真正便于维护。标准结构是先喷砂再阳极氧化的铝板，比轧制原面更能遮盖搬运痕迹，也能承受这类产品在工业电气柜内的日常清洁。
Where your unit is liquid cooled, the plumbing decides the design. Inlet, outlet and drain openings are laser cut to your hose routing and drip-tray position instead of a generic pattern, because the difference between a port you can tighten with the lid fitted and one you cannot is usually about 20 mm of placement. We also check that the drain can actually drain — a port sitting above the lowest point of the base is decoration.
若您的产品采用液冷，管路就是设计的出发点。进水口、出水口与排水口按您的软管走向与接水盘位置激光开孔，而非套用通用孔型——能盖上盖后拧紧的接口，与拧不了的之间，往往只差约 20 mm 的落位。我们还会复核排水口是否真的排得出去：位于底座最低点之上的排水口只是装饰。
Nothing here is stock. Every chassis we ship began as your module outline, your airflow figure and your indicator layout, and the drawings behind it are drawn and revised free of charge until you sign them off.
这里没有现货件。我们交付的每一台电源外壳，都起自您的模块外形、风量数据与指示灯布局；其图纸由我们免费绘制并修改，直至您签核为止。

Engineering Highlights
工艺要点
Ports Cut From Your Plumbing
按您的管路开孔
Coolant inlet, outlet and drain positions follow your hose routing, fitting size and drip-tray geometry, so every connection stays reachable and tightenable with the cover fitted. We check each port on the first article using the actual fittings rather than a drawing overlay.
冷却水进口、出口与排水口的位置遵循您的软管走向、接头规格与接水盘几何，确保每个接头在盖体装好后仍然够得着、拧得动。首件上我们用真实接头逐孔校核，而不是拿图纸套图核对。
Honeycomb Vents Without a Soft Panel
蜂窝散热孔，面板不塌
At equal ligament width a hexagonal array leaves more open area than round holes, which is why we use it on hot chassis. The ligament still has to stay wider than the sheet thickness or the panel buckles, so we size the array against your airflow figure and check flatness after forming.
在同等孔桥宽度下，六方阵列比圆孔留出更大的开孔率，这正是我们在发热电源外壳上采用它的原因。但孔桥必须比板厚更宽，否则面板会失稳起皱——因此我们按您的风量数据确定阵列尺寸，并在成型后检查平面度。
Silkscreen Where It Survives
丝印放在留得住的位置
Legends are printed after finishing rather than before, so they bond to the anodized or coated surface instead of sitting underneath it. Port names, ratings and warning marks stay readable through cleaning, and where a label has to face a solvent we switch that position to laser marking.
标识在表面处理之后而非之前印制，因此与阳极氧化层或涂层结合，而不是被覆盖在其下方。端口名称、额定值与警示标记在多次清洁后依然清晰；若某处标识需接触溶剂，我们对该位置改用激光打标。
Grounding Kept Continuous
接地保持连续
Anodizing insulates, which is what you want across most of the shell and exactly what you cannot have at a grounding point. We define those points at drawing stage and keep them masked or machined, so continuity and bonding survive the finishing line.
阳极氧化层是绝缘的——对壳体大部分区域这是优点，但在接地点上绝不能有。我们在图纸阶段就明确接地点并做遮蔽或后加工，使导通与搭铁在处理后依然存在。

Frequently Asked Questions
常见问题
What is the minimum order quantity?起订量是多少？
MOQ is 1 piece. A power chassis usually has to clear its own plumbing, panel layout and indicator positions before anyone signs it off, so we prototype first and quote the batch from the validated design.1 件起订。电源外壳这类零件，通常要先确认管路走得通、面板排得下、指示灯位置对，才会有人签核——所以我们先打样，再以验证后的设计报量产价。
Can you position the coolant ports and drain for our plumbing?能按我们的管路布置冷却水口和排水口吗？
Yes. Inlet, outlet and drain openings are cut to your hose routing, fitting sizes and drip-tray position, and we also check that the drain sits at or below the lowest point of the base so it can actually drain. Each port is verified on the first article with your real fittings.可以。进水口、出水口与排水口按您的软管走向、接头规格与接水盘位置开设，并检查排水口是否处在底座最低点或其以下，使它真的排得出去。首件上会用您的真实接头逐孔校核。
Aluminium or steel — which should I choose?铝材还是钢材，该怎么选？
Aluminium for heat spreading and handling weight, which suits most power chassis. SPCC cold-rolled steel is cheaper per part and carries magnetic shielding better, and SUS304 is the call for wash-down or coastal duty. Tell us the environment and the heat load and we will quote one.若看重散热扩散与搬运重量，选铝材，这也是多数电源外壳的选择；SPCC 冷轧钢单件成本更低，低频磁屏蔽也更好；需冲洗或沿海服役则选 SUS304。告知服役环境与热负荷，我们会给出报价方案。
Will anodizing break my grounding?阳极氧化会影响接地吗？
It will if grounding points are left undefined, because an anodized layer is electrically insulating. We identify every bonding point at drawing stage and keep those areas masked or machined, so they stay conductive through finishing.如果图纸没有明文规定接地点，就会有影响——阳极氧化层是电绝缘的。我们在图纸阶段明确每一个搭接点，并对这些区域做遮蔽或后加工，使其在处理后仍保持导电。
How much airflow can the honeycomb vents handle?蜂窝散热孔能过多少风量？
Open area is sized against the airflow and available static pressure you give us, then checked against the stiffness the panel needs. We do not guess a figure: send the heat load and fan curve and the pattern is sized from those numbers.开孔面积按您给出的风量与可用静压确定，并与面板所需刚度一起校核。我们不会凭估计给数字：请提供热负荷与风扇曲线，孔型由这两项数据算出。
What do you need to quote?报价需要哪些资料？
Step files or drawings are ideal, but a marked-up photo, a hand sketch with key dimensions or a sample unit is enough to start. We reply with a DFM review, drawings and a factory-direct quote within 24 hours.有 STEP 文件或图纸最好，但标注过的照片、带关键尺寸的手绘草图或一台样机也足够起步。我们 24 小时内回复 DFM 评审、图纸与工厂直供报价。
